Overview of Gastric Bypass Surgery Treatment India

Gastric bypass surgery is a medical procedure which is performed on people who are obese. Gastric bypass surgery is performed on an obese person to reduce their health condition which is severely affected by obesity. The patient who has serious health conditions due to being overweight can benefit from this surgery. Gastric bypass surgery is usually recommended to those people who have a body mass index (BMI) of 40 or a BMI of 35-39.9 with weight related health problems such as type 2 diabetes, breathlessness, or high blood pressure. Gastric bypass surgery changes the path of food digestion and limits the food capacity that allows absorption of low calories. The main purpose of gastric bypass surgery is to reduce weight by reducing the capacity of food intake of a person at one time. This surgery allows them to feel full sooner than before. Gastric bypass surgery is a type of major surgery and it is only allowed after the obese person has gone through all the alternative ways of weight reduction techniques like dieting, exercise etc. It also carries some risk and has chances of complications during or after surgery. Patients who undergo this surgery need to make changes in their eating habits and lifestyle to maintain their weight loss. 

Types of Gastric Bypass Surgery Treatment India

There are several types of gastric bypass surgery. These are:

  • Roux-en-Y Gastric Bypass (RYGB)
  • Mini Gastric Bypass (MGB)
  • Biliopancreatic Diversion with Duodenal Switch (BPD-DS)
  • Single Anastomosis Gastric Bypass (SAGB)

Roux-en-Y Gastric Bypass (RYGB)

In this surgery, the small pouch of the stomach is formed at the top which is then connected to the small intestine. The remaining part of the stomach and some part of intestine is bypassed which restricts the amount of absorption of nutrients.

Mini Gastric Bypass (MGB)

In this surgery, the procedure is the same as the RYGB but the stomach pouch is usually longer and narrower than usual which is then connected to the small intestine directly. The MGB procedure is simpler and faster than RYGB.

Biliopancreatic Diversion with Duodenal Switch (BPD-DS)

In this, the large part of the stomach is removed and a small pouch of the stomach is connected with the lower part of the intestine. also the upper part of the small intestine is connected with the lower part of the intestine. This surgery allows a massive amount of weight reduction but also can lead to nutritional deficiency in future.

Single Anastomosis Gastric Bypass (SAGB)

The SAGB is almost similar to the RYGB procedure but it only creates a single smaller connection between the stomach pouch and small intestine. It requires less time than RYGB.

Procedure of Gastric Bypass Surgery

The steps of procedure for gastric bypass surgery:

Anesthesia: the surgery is performed under the effect of anesthesia to reduce the pain and discomfort during the procedure.

Incisions: the long or short incisions are made according to the type of surgery performed. The large incisions are made for open surgery.

Creation of the Stomach Pouch: The surgeon will separate a small portion of the upper stomach to create a smaller pouch. This pouch will serve as the new stomach and will hold a smaller amount of food than before.

Diverting the Small Intestine: The surgeon will then divide the small intestine and connect the lower end of the divided intestine to the newly created stomach pouch. 

Bypassing a Portion of the Intestine: The upper part of the divided small intestine is then connected further down the intestine, bypassing a significant portion of the small intestine.

Closure and Recovery: the surgeon closes the incisions and applies the medications to prevent any infection. After the surgery, the blood pressure and heart rate is monitored and pain is managed.
